"Unlike Sub Saharan Africans, North Africans have a similar level of Neanderthal DNA to South Europeans and West Asians, which is pre Neolithic in origin, rather than via any later admixture with peoples from outside of North Africa during the historical period."
I understand this is what is widely believed, however it is also contradicted by this article:
(PRINCETON EDU) New study identifies Neanderthal ancestry in African populations and describes its origin Aaron Wolf, Lewis-Sigler Institute for Integrative Genomics
Basically: "The Princeton researchers termed IBDmix a “reference free method” because it does not use an African reference population. Instead, IBDmix uses characteristics of the Neanderthal sequence itself, like the frequency of mutations or the length of the IBD segments, to distinguish shared ancestry from recent interbreeding. The researchers were therefore able to identify Neanderthal ancestry in Africans for the first time and make new estimates of Neanderthal ancestry in non-Africans, which showed Europeans and Asians to have more equal levels than previously described."
"Kelley Harris, a population geneticist at the University of Washington who was not involved in the study, noted that the new estimates of Neanderthal ancestry using IBDmix highlight the technical problem in methods reliant on reference panels. “We might have to go back and revisit a bunch of results from the published literature and evaluate whether the same technical issue has been throwing off our understanding of gene flow in other species,” she said." 2001:1C00:1E31:5F00:2D98:BB93:3989:7FEE ( talk) 07:57, 12 October 2022 (UTC)

Hi, the article has many repeats in various sections, so I moved everything to the appropriate position. Secondly, I did not revert to a previous version, but readded the information that was removed by prior editors. I encourage users to look at the state and structure of the article before the changes I implemented, it reads badly and omits data that was shown prior, and has numerous word for word paragraph repeats which I was fixing. Furthermore, the studies I added were appropriate to the page, all dealing with North African genomes. Not only this, but I actually read the studies included, and the summaries were not exactly accurate so I updated them. There were portions of this entry that were leaning heavily towards anything 'Arab, Middle Eastern and Haplogroup J' which is bad faith as information should be distributed and presented fairly in the appropriate places. I also removed the J1 image as it is already on the main article which is linked and irrelevant here. Thanks, looking forward to coming to agreements, discussing things further and resolving any more issues.

Other things is that we can't have verbatim paragraphs in the lead summary also be present in the Genetics section (where it should be) which is why I moved it, I had also added the latest info dealing with Tunisian paternal ancestry from 2021 which gives a different perspective to the previous data shown. The page should not have data dealing with Autosomal DNA in the Y-Chromosome sections or vice versa, and we should keep all relevant information structured together and show both perspectives, instead of being one sided to certain narratives.

Hi all, this is my first edit of this page.
I've made some edits to the section discussing the 2012 genetic study of North African populations. The previous version of the article seemed to suggest a definitive conclusion that there was no ancestral linkage between modern North Africans and inhabitants from 50,000 years ago. However, the paper itself does not make such a firm assertion, and this could mislead readers.
Here are the main reasons for the edits:
-The edit ensures that the language used doesn't suggest a complete disconnect between present-day North Africans and ancient populations from 50,000 years ago, as there is no such evidence or statement to this effect made in the paper. The new wording should promoting a more nuanced understanding.
-The original phrasing in this section might also lead readers to infer that North Africans have only been in the region for 12,000 years. This edit seeks to provide clarity, especially for those unfamiliar with genetic studies and regional history. The edit emphasizes that the presence of a dominant genetic signature from 12,000 years ago doesn't mean there's an absence of earlier genetic contributions.
Please let me know of any feedback on this. Mrmisr ( talk) 22:49, 25 September 2023 (UTC)
